Billy called me yesterday and he is going to meet with us one day this week to test it out on my system. We will see how it goes. I will take pics.

 The orfice size seems to be critical Larry, and is determined by overall flow and pressure at the end of someones hose. Billy runs 3/4 inch hose, I run 5/8, and it is said you run 1/2 inch hose ?  Thus, your orfice size may turn out to be different then mine ?
